Oxoguanine glycosylase - Wikipedia
OGG1 is the primary enzyme responsible for the excision of 8-oxoguanine (8-oxoG), a mutagenic base byproduct that occurs as a result of exposure to reactive oxygen species (ROS). OGG1 …
Reassessing the roles of oxidative DNA base lesion 8-oxoGua and …
2025年1月1日 · ROS oxidize Gua in the guanine-enriched region to form 8-oxoGua, and OGG1 recognizes and excises 8-oxoGua. The generation of the AP site in the promoter region leads …
OGG1-initiated base excision repair exacerbates oxidative stress ...
2018年5月24日 · Results showed that OGG1-BER further increases the levels of ROS-induced DNA damage by generating repair intermediates, leading to PARP1 overactivation and cell death.
MTH1 inhibition synergizes with ROS-inducing agents to trigger …
2024年6月1日 · ROS-inducing agents in combination with MTH1 inhibitors promote tumor cell parthanatos via OGG1-BER. A small amount of 8-oxoG integrated in the genome caused by …
